SPECIFICATION forming part of Letters Patent No. 288,920, dated November 0, 1883,

n nmitn filed March 13, 1883. (N0 model.)

To (LZZ whom itmay concern Be it known that I, FRANK Bunnows, a citizen of theUnited States, residing at VVashington, in the District of Columbia, have invented certain new and useful Improvements in Door and Window Fasteners, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to improvements in devices for securing doors and windows; and it consists in a metallic lever provided. with a head at one end having shoulders or trunnions adapted to fit into and turn in bearings on the upper part of a floor-piece, having a central longitudinal slot to receive the lever in its closed position, and pointed at the lower end for the purpose of entering the floor or top of a window'sasln The details of construction and arrangement of the several parts will be hereinafter more fully set forth in the specification, and pointed out in the accompanying drawings, in which- I Figure l is a perspective view of the lever and door-piece; Fig. 2, a sectional View on the line as m, Fig. 3, showing the parts in position preparatory to securing the pieces in their closed or locked position; Fig. 3, a perspective View of the parts in position and locked together, and Fig. 4 a detail perspective view of the floor-bar.

Referring more particularly to the drawings, the fastening-lever A is made of cast or malleable iron, of suitable length and size. A- portion of this lever is cut away on its under side, so as to leave a shoulder, a. The up per end of the lever terminates in a wedgeshaped head, B, having projections b, rounded ed to turn in a bed or seats on the floor-piece C. The upper part of the head is cut away centrally, as at B, so as to leave the projections 0 at each side thereof. The floor or lower holding-piece, G, has a longitudinal slot, F, to receive the lever A in its closed or secured position. The upper end of this piece 0 is cut away centrally a portion of its length, so as to leavethe arms D,which have the ends grooved, as at (Z, forming a bed for the trunnions b to rest in and turn upon, the shouldered part a of lever A resting on the seat between the arms D when the-lever is turned down into the slot F.

The primary object of the device is to fasten doors; but it may be used equally well for the lever being inclined to bar 0 at an angle of about forty -five degrees, the projecting points 0 just touching the wood, or inserted in the depressions g, as shown in said figure. The lever A is then depressed until it enters the slot F. This causes the points 0 to enter the wood, or come up against the upper end of the depression 9 in the plate G, and at the same time the points 0 areforced slightly into the floor. Any pressure from the outside acts in the direction of the length of the lever and bar, and therefore serves to force the projections 0 farther into the floor, and prevents an entrance being effected unless the door is broken or thrown off the hinges.

To fasten a window, the piece C is placed on top of the lower sash, near the casing, and the same operation gone through with the lever and bar as described for the door. As the lever F cannot be reached and pushed out of place with a knife or wire, a great advantage is obtained over the ordinary window-fastenings. To release and remove the parts of the fastener, it is only necessary to lift up the lower end of lever A, which causes the trunnions to turn, and the parts assume the position shown in Fig. 2, when they can be readily removed.

The better to prevent injury to a door or window frame, I place a metal plate, G, on the door or window, at a suitable height, corresponding with the length of lever A. This plate has depressions 9 formed therein to re ceive and hold the projections c of lever-head B. This plate is permanently secured to the door, and is therefore a guide to the proper position for the lever A. I may also have a corresponding plate placed in the floor to receive the ends of bar 0. The door-plate also prevents boring through the door to reach the lever A. The entire length of a door-fastener for dwellings need not exceed four inches, and for a window three inches is sufficient. For warehouses, stores, &c., the size may be increased as deemed necessary. I

This device is simple in construction, can be readily put into use or removed, easily carried, as it weighs but three or four ounces, and therefore presents a vade-mecum for persons traveling and exposed to robbery by the insecurely-fastened doors and windows of h0- tels.

Having thus described my invention, what I claim is- 1. Afastening device for doors and windows, consisting of a lever, A, and bar 0, the bar being slotted longitudinally, and provided with trunnion-beds at one end, the lever having a wedge-shaped head provided with trunnions adapted to rest and turn in the trunnion-bed of said bar, substantially as and for a presence of two witnesses.
